Do-it-yourself barrier lock repair

In detail: do-it-yourself barrier lock repair from a real master for the site my.housecope.com.

Needless to say, home security today is a special expense item for a property owner? Unfortunately, this applies not only to the owners of suburban real estate, but also to apartments in the city. When choosing a door, many people pay great attention to the class of burglary resistance and fire resistance. Indeed, a durable door leaf provides some degree of protection against tampering.

However, the lock used on the door is an equally important security feature. If we evaluate the locks according to the statistics of burglaries, then the manufacturer of the barrier will definitely rank first in terms of reliability. A popular solution for private real estate today is Barrier-4 (4 class of burglary resistance). However, the installation of barrier locks on many models of modern canvases can be difficult.

It should be remembered that the lock itself is overhead. Therefore, it will be fixed to the door by means of a bolted connection. It is important that the thread is immersed to a depth of at least 8 mm.

If we take into account that steel more than 4 mm is very rarely used in the production of door panels for an apartment, then the installation of the proposed lock becomes problematic.

Special overlays will allow you to get out of the situation. They are made of steel and are installed directly into the door leaf. This makes installation of the lock possible in principle.

The reliability of the lock depends not only on the manufacturer, but also on the correctness of its installation. Professionals recommend that you first mark the place where the lock will be installed. This can be done with a simple pencil.

If the door surface is glossy, use masking tape to mark with a pencil.

There must be a required 2 mm gap between the lock and the door jamb. Otherwise, when closing and opening the bolt, problems may arise (when placed close to it, the bolt may jam).

The assembly of the lock is carried out as follows:

the body is bolted;
the lock part is assembled (the correctness of its work must be checked with a key before proceeding to the next part of the work);
a bolt is installed;
the bolt is locked with a bolt supplied with the lock.

Newcomers to the installation of locks may have difficulties in assembling the lock part. As a general rule, it is appropriate to use a screwdriver to engage the retaining ring. It is only important to find a solid and reliable support for it.

The first attempts to make something out of the brought slabs. Although there may be attempts, the material costs money and the margin for error is as much as there is money in your pocket. Train at your own expense, as they say.

Therefore, each board is carefully examined and measured, the proverb about seven times measure in action.

The work itself is not tricky, creative, there are several boards and you need to pick them up so that it looks beautiful and there is no overrun. All adjustments to the size and trimming are done with the minimum possible removal of material, just sawed off a bit here, cut a little there with a chisel.

So I lived to see my workshop, which needs to be equipped and supplemented with various instruments for a long time and persistently.

But the main thing is there is a warm room, although not your own, there is where to work until they are kicked out.

This warehouse is quite spacious, if you remove everything you don't need, so you have to do a lot to get to work at least somehow. And the first thing I did was take out too much and started assembling a large desktop.

Igor Shubin at his site in the village "Lesnoye"

Igor was looking for a forest suburban area, and among others he got this one. And not only is it an impassable forest, but also in the middle of the site - 6 meters of slurry from a small stream. Because of this swamp, the future owners could not cross to the other side of the site to inspect the boundaries of the property.

The uniqueness of this door lock is in the thickness of its steel body, and in the statistics of criminal burglaries in St. Petersburg. The main advantage of any mechanism is its simplicity and reliability. It is simpler than the castle Barrier 4, it is difficult to come up with it, you see for yourself, there are very few details. Another advantage of any locking system is its small size and compactness.The height of this lock, only 74 mm, with such a high class of burglary resistance, like 4, is very small, and there is always a place for this lock on any door.

The main condition for the reliability of this lock is correct installation. the dominance of doors made of thin steel makes it almost impossible to provide a decent installation, and in particular - threaded fasteners.

To solve this problem, foreman Mikhail, aka Mikhail Vyacheslavovich Sukhaninsky, created a manual for the possibility of installing this lock on a door made of thin steel

To begin with, we created a cut of a standard door block made of thin steel, a prototype of a steel door in new buildings in St. Petersburg, on which the Barrier 4 lock is to be installed.

The body of the lock is applied to the back surface of the door leaf, and the markings are applied with a sharply sharpened soft pencil. If the door leaf covering is dark, then it is possible to place it for marking. stick on masking tape.

It is very important, when placing markings, to take into account the need to ensure a gap between the end of the lock case and the plane of the door frame adjacent to it.

Let's omit the technology for producing the necessary holes, each master has his own technique. We will assume that the holes necessary for installing the lock have been created in accordance with the markings made.

It should be noted that it is more convenient to markup when the door block is open.

The lock case is fastened with M8 screws. These are huge screws and need a thread depth of at least 6mm to be effective. If the thickness of steel used in the manufacture of the door block is not more than 1.5 mm thick, such a thread cannot be created without the use of special reinforcements.

Inside the door leaf, special steel elements are laid, which on one side increased the thickness of the steel in the right place, and on the other side rested against the outer sheet of steel.

On the outside of the door, a hole with a diameter of 22 mm is drilled to secure the protective strip, which serves as a keyhole.

In disassembled form, this overlay looks like this, and there are no need for a lot of words to describe it. The assembly of the protective strip, on the outer steel sheet, is shown just above.

So that the bolt does not fall into the gap, between the door leaf and the door frame strip, a steel gasket, 4 mm thick, should be used. Which is fully consistent with the size of the lock body.

Two images show the location of the bolt in the door frame before installing the gasket between the lock body and the door leaf, and after.

We fasten the lock case with screws to the door leaf, and insert the security cylinder mechanism into the grooves of the same lock case.

Within the framework of this article, I would like to conduct a comparative test of two overhead locks with a cylinder locking mechanism. These are Barrier-2 and Barrier-2M locks, manufacturer LLC "Polivektor" St. Petersburg.

Photo 1. View of the castle Barrier-2. Red arrows with numbers:
1 - a metal plate is marked, which serves as a protection for the cylinder mechanism and is an element for fastening the lock;
2 - the handle is marked, with the help of which the crossbar is moved.

Photo 2. View of the castle Barrier-2M. Red arrows with numbers:
1 - a metal plate is marked, which serves as a protection for the cylinder mechanism and is an element for fastening the lock;
2 - the handle is marked, when turned, the deadbolt moves.

Photo 3... View of the castle from the outside.

Photos 1, 2 and 3 are taken from the manufacturer's website ( LLC "Polivektor" ). As you can see in photos 1 and 2 (see marks 2), the locks differ only in the handles that move the crossbar. In the Barrier-2 lock, to open it, you need to unlock the bolt by lifting the handle up and then move the bolt. This procedure could be carried out from the outside of the door by drilling a hole through which the handle was lifted and then the bolt was moved to the side. In the Barrier-2M lock, the handle design has been changed, it has become rotary. Thus, the manufacturer eliminated the possibility of criminal unlocking the lock in the above way. Another difference is the way the cover plate is attached. Both models have the same cylinder mechanism. The secrecy of the lock is provided by 3 rows of pins, 3 pins in a row. The design of the code mechanism is as follows: a steel ball, they are all of the same diameter, serves to transfer information from the key to the code pin; code pin; support pin; spring.

Photo 4. View of the pins of the cylinder mechanism of the Barrier locks. Red arrows with numbers indicate:
1 - code pins (steel balls);
2 - support and code brass pins, differ from each other only in size;
3 - springs.

Cutting of key secrets has 4 standard sizes, secrecy is provided by 9 pins. The step of cutting the secret is 0.5 mm. The total error is 0.3 mm. Thus, the secrecy is 4 9 = 262144 secrets. After making a series of locks using the entire number of secrets, the angle of the pins is changed and a new series is made. The design of the lock is simple, the quality of the workmanship of the lock parts, assembly and painting is satisfactory.

The lock comes with installation instructions, according to which a hole is made in the door leaf for the cylinder mechanism. Next, the lock is attached with three screws to the door leaf and with a protective plate installed outside the door and fastened to the lock with three screws. With such an installation, by removing the protective plate, access to the cylinder appears, which can be acted upon by various burglary methods. The plate can be removed in the following ways: knock down (in the Barrier-2 locks); drill out the attachment points (in the Barrier-2 and Barrier-2M locks); unscrew and unscrew the fastening screws with a flat key (in Barrier-2M locks). These methods were not just invented by me, but by thieves, burglars. Here are typical real life examples (the most common hacking methods).

Photo 5... View of the Barrier-2 castle, which was knocked out into the interior of the apartment by blows on the cylinder mechanism. The fastening points of the lock could not withstand the applied force.

Photo 6... View of the Barrier-2M castle, opened in the following way. The protective plate on the outside of the door was squeezed out a few millimeters, which made it possible to slip a flat key under it and unscrew the nuts securing the protective plate. After that, the thief bent back the metal plates covering the holes with pins (marked with red arrows) and removed the springs, support pins and code pins. After that, the lock can be opened with any key. I think it's time for the manufacturer to change the design of the cylinder for the door locks, especially since there is no need to invent anything. At the Barrier in the S-300 and S-600 models (safe versions), a protective hood is put on the cylinder, which excludes the above-described method of breaking the lock.

Photo 7... An enlarged view of a cylinder mechanism with a bent plate covering the hole with pins.

Most of the thefts are committed due to improper installation of locks on the door. But these are claims not to the manufacturer of locks, but to the door doors. No one has installed wooden entrance doors for a long time. I consider the correct installation of a lock in a metal door when only a 9 mm diameter hole for a key is visible from the outside of the door. All fasteners of the lock must be made inside the door leaf. Thus, the outer metal sheet of the door itself will additionally protect the lock.

When installing Barrier locks in accordance with the manufacturer's instructions, several methods of breaking are possible, which will be discussed below.

The first way the most difficult and time-consuming is drilling the key guide in order to remove the security elements of the lock (pins).

Photo 8. View of the cylinder mechanism of the Barrier locks. The red arrow indicates the guide post inside the cylinder. The stand is protected from drilling with a steel ball.

The stand is not only a guide for the barbed wire, but also prevents the pins from falling out of the cylinder. To drill the rack, a guide tube with an outer diameter of 8 mm and an inner diameter of 5 mm was used. The stand was “damp”, so a conventional drill R6M5 with a diameter of 5 mm was used (photo 9).

Photo 9. View of the guide tube and drill with which the cylinder post was drilled.

To unlock the lock by drilling the rack, the following steps were performed:
1. By drilling into the rack from the side, remove the steel ball.
2. A guide tube was inserted into the key hole and a rack was drilled through it.
3. The guide was pulled out sharply. Under the action of the springs, the code pins (steel balls) fell out of the cylinder.
4.Using tweezers and a wire hook, the support pins and springs were removed from the cylinder.
5. Opened the lock with a key from another Barrier lock.

Photo 10... View of the cylinder mechanism after drilling. A red arrow indicates that there are no strut or pins in the cylinder.

Photo 11... View of the cylinder with the cover removed after drilling the rack.

It was not difficult to remove the steel ball from the rack and drill the rack. This procedure took no more than two minutes. I had to tinker with removing the support pins and springs from the cylinder. The total time for unlocking the lock using this method was 23 minutes. This unlocking method is suitable for both Barrier 2 and Barrier 2M locks.

Second way - drilling of the fastening screws of the cylinder mechanism.

Photo 12... The red arrow indicates the location for drilling into the mounting screw of the cylinder mechanism. Drilling is done at an angle and the shielding washer does not interfere.

Photo 13... Same as photo 12, but we drill the second fixing screw.

Photo 14... View of the cylinder mechanism, after drilling the attachment points. The red arrows mark the cylinder attachment points.

Photo 15... This is what the lock looks like after the above procedure.

The essence of the method for unlocking the lock in this way is as follows, after drilling out the attachment points of the cylinder, pull it out of the lock body (it is enough to move it by 3 mm) and through one of the holes we move the bolt to the “unlocked” position. We managed to open the lock in this way in 3 minutes. 15 sec.

Photo 16... View of the lock after removing the cylinder mechanism. Red arrows indicate the attachment points of the cylinder mechanism.

The third way (applies only to Barrier 2) - drilling a hole in the lock body in order to raise the deadbolt lock and move the deadbolt.

Photo 17... View of the castle Barrier-2. Red arrows and numbers indicate:
1 - a hole in the lock body, which must be drilled in order to remove the deadbolt lock and move it to the unlocked position;
2 - protrusions on the inner side of the crossbar, which must be acted upon through the drilled hole in the lock body, the direction of the force application is indicated by blue arrows;
3 - crossbar, blue arrow shows the direction of movement to the “unlocked” position.

The manufacturer of the Barrier locks made an upgrade of the Barrier 2 model, changing the handle and the deadbolt unlocking system, in my opinion, in order to eliminate the possibility of criminal picking of locks in the way described above (see method three). The new model was named Barrier 2M (modernized).

What do we see in practice? But in practice, it turned out that the lock is much easier to open than in the Barrier 2. How exactly, read below fourth way.

Photo 1 8 ... View of the lock Barrier 2M with a rotary handle.

Photo 1 9 ... Castle construction. The red arrow shows the deadbolt locking mechanism. To open the lock, it is enough to drill one hole by drilling the part indicated by the arrow.

Photo 20 ... Complete lock. We will drill at an angle, incl. the protective plate is not a hindrance to us again.

Photo 2 1 ... All the metal of the lock is "raw", it can be drilled just fine. The red arrow indicates the hole in the projection of the rotary knob.

Photo 2 2. The red arrow indicates a hole drilled with a simple drill with a diameter of 11 mm.

Photo 2 3 ... The red arrow shows the deadbolt locking mechanism, or rather what remains of it after drilling.

Photo 2 4 ... After drilling the deadbolt locking mechanism, the deadbolt is moved through the same hole and the deadbolt is in the “unlocked” position.

Photo 2 5 ... What's left of the rotary knob.

Photo 2 6 ... This is what your lock will look like when unlocked as described above. The time for unlocking the lock using this method was 2 minutes. 35 sec.

If any of the readers knows specific cases of thefts from apartments where Barrier locks were installed, write in order to generalize the negative experience and refer to the manufacturer of locks to eliminate the shortcomings.

Unlocking the lock using the manipulation method is possible, but it is very difficult and, due to the large amount of time required for this, is not considered here. We also do not touch the cutting machine, gas cutter and electric jigsaw.

Usually at the end of the tests I give recommendations on how to protect the castle, but in this case it is not possible, because it is necessary to change the cylinder locking mechanism and the actuator, i.e. the whole castle.

Conclusions: The time of the criminal picking of the lock is less than 5 minutes. In accordance with the requirements of GOST 5089-2003, the Barrier-2 and Barrier-2M locks correspond to class 1. These locks have low security properties and are designed to lock the doors of utility rooms and internal doors in apartments and offices.

This test was expanded and supplemented, and the preliminary test carried out was sent to the Polivektor plant to review and correct the shortcomings of the lock. Initially, a comparison was made of the Barrier and GERDA locks, similar in design, but due to the large amount of information, I divided the article into two parts, this one and about GERDA ... You can find the answer of the plant's representative here comments of LLC "Polivektor" on the above.

P.S. The representative of the plant reports that he did not learn anything new about his locks, i.e. knowing about all the drawbacks of locks, they were produced and I think they will be produced, tk. purchased locks Barrier-2 and Barrier-2M are produced to this day. Where is the logic? If the Barrier-2M castle replaced the Barrier-2 castle, which had shortcomings, then why is a deliberately bad castle still being produced? See photo 27, these are the passports of the locks I bought in September 2005. The release date of the lock "Barrier-2" - August 02, 2005, "Barrier-2M" - August 31, 2005

Photos 27... View of two passports to the locks. Red arrows with numbers mark the release dates of the locks.

This is the Uncut Barrier. What kind of locks do your loved ones have?
